If the addition of non-stock grips caused a problem, it had to be because of a speed loader cut out. Otherwise the grips lay against the flat and keep the pivot pin from vibrating out a bit while firing, which would be the only problem that would require a screw. There would not have been a problem with factory style grips as I am sure Smokinggun can attest. There could, I suppose, be a problem with poorly designed after-market grips. And, the grips have to be removed for any disassembly. Thanks for your thoughts, Anachronism.
